What are the main causes of stomach pain after drinking alcohol?

The main causes of stomach pain after drinking alcohol include: 1. Alcohol irritation: Alcohol directly affects the gastric mucosa, causing damage and resulting in pain. At the same time, alcohol stimulates gastric acid secretion, worsening the damage to the gastric mucosa. 2. Gastrointestinal diseases: Patients with conditions such as gastritis or gastric ulcers may experience worsening of their existing condition due to alcohol consumption, leading to increased pain. 3. Abnormal gastrointestinal motility: Alcohol may affect gastrointestinal motility, leading to dysfunction in gastrointestinal movement and causing discomfort. 4. Increased burden on the liver: Excessive alcohol consumption increases the burden on the liver, which may indirectly affect stomach health and cause pain. 5. Improper eating after drinking: Overeating or binge eating can increase the burden on the stomach and may also lead to pain.
